Rauta introduced sandwich panels with Cor-Ten weathering steel external facing.
Ruukki Patina gives the façade a noble appearance and can also reduce the building’s energy consumption and CO2 emissions by up to 20%. The core is made of non-combustible and environmentally friendly mineral wool with a low coefficient of thermal conductivity, which provides excellent thermal insulation of the panel. The special configuration of the core ends increases the tightness and provides high sound insulation, and the patented shape of the joints prevents their internal corrosion.
The external facing of the panel is made of 0.7 mm thick Cor-Ten steel, and the internal one is made of 0.5 mm thick color-coated steel.
“A unique property of sandwich panels with Cor-Ten steel facing is the ability to independently repair minor scratches due to the formation of a new patina,” – said Andriy Ozeychuk, Rauta Director. – “This allows the building owner to worry less about the appearance and save on maintenance”.
The new product is available in thicknesses from 150 to 230 mm and is supplied with untreated Cor-Ten steel facing, which will allow the building to change its appearance over time.
